Twitter Bg Restorer
Twitter Bg Restorer is a chrome extension to restore Twitter's background.

The extension was created when Twitter removed the ability to set the background image/colour of the homepage in 2015, instead giving everyone a boring, eye-searing white background. Given Twitter's monumental whitespace, this made looking at the timeline difficult.

There also exists a version for Mozilla Firefox.

It has been featured in The Guardian, VentureBeat Gizmodo and Lifehacker.
